"I've heard the predictions. I've seen the polls. But let me tell you this: we will do so much better than anyone thinks.

"In those seats where we are out in force, making our case loudly and proudly, we are the ones making the weather. I've seen it for myself in Liberal Democrat seats across the country.

"We are showing that with hard work, strong local campaign teams and a record of delivering for people in national and local government, we can and will win."

Rallying support ahead of what is predicted to be one of the closely fought elections in a generation, the Lib Dem leader said the UK's return to growth after economic peril was down to policies the party had a hand in.

"The recovery would not be happening without the Liberal Democrats," Clegg added.

"More than 1,400 gay people are now married – hopefully happily. More than two million apprentices are learning the skills they need for their careers.

"1.6 million boys and girls are getting a hot, healthy lunch every day at school.

"More than 26 million people on low-and-middle incomes have had their income tax cut every year, worth more than £800 from next month.

"And more than three million of the lowest paid workers are no longer paying any income tax at all."

Appealing to undecided voters, Clegg said the Conservatives were "unfair" and Labour would "ruin the economy".

And of other possible coalition partners, Clegg warned "If you think a vote for UKIP, or the Greens, or the SNP is harmless – it isn't."
